WITNESSES AJOHN vr. wmrrna, or roIN'r Toall whom 'it may wnoomt'.

Be it known that we, JOHN F. Wmrrnn and HENRY D. Femm, citizens .of the United States, residing, respectivel at Point Richmond, in the county of Cl'mtra Costa, and Berkeley, in the county of Ala meda, State of California, have invented new and useful Improvements in Machines for Forming Jackets on Piles, of which the lo following is a s ecification.

The object o the present invention is to provide amachine for forming around lpiles Jackets preferably of plastic material with an outer coating or sheathing.

In the accompanying drawing, Figure 1 is a plan view of the mechanism for turning and feeding the pile; Fig. 2 is a side view of the wheel, a gear being removed; Fig. 3 is an end viewof said mechanism; Fig. 4 is a plan view of the apparatus for feeding the plastic material and sheathi the pile being broken away.; Fig.. 5 is a si e view ofthe same; Fi 6. is a transverse vertical section on the line 6--6 of Fig. 4.

Referring to the drawings, 1 indicates a truck, mounted on wheels 2, which are *Y ada ted totravel onA rails 3. Upon said truc so Said. l cure to a shaft v8 rotating in bearings 9 on' is supported4 an electric motor 4, the kshaft 5 of which carries a lpinion 6 which mesheswith a largegear wheel 7 and communicates a comparatively slow motionI to ear wheel. Said gear wheel 7 is sestandards 1 0, and on said shaft is secured a pinion 11,@which meshes with a gear wheel 12 which is secured to converging Tbars 13,

. the 'inner or conveiging ends of said bars I being secured to a 1 rame 14 which in'turn is secured to a shaft 15 in a bearing 16 and car ing a bevel gear 17 meshing with a beve gear 18 on a shaft 19 in a bearing 2O and carrying a gear wheel 21 which meshes with a rack 22 located parallel with the rails 3.

It willv be seen that by means of this mechanism the converging bars are given a rotary motion and the t-ruck is at the same time given a longitudinal motion, the rela tive speeds of 'said lmotions beingy determined by the proportions of the intermediate mechanism, which may be of any desired size.

tive movement by -hooks 26, which are'4 the sides of the pile., In this way the pi e also is longitudinal motion.

The ybody of the pile is supported upon two rollers 30, shown in Fi 4 and 5, the peripheries of said rollers preferably being rounded to allow of a sliding motion of the pile thereon. Said rollers are rotatably supported in bearings 31 on av table 32, which given a rotary and` is secured so asv to be rotatable about a vertical axis by awvertical bolt 33, passing given a slight rotary movement by mechanism hereinafter described.

Supported upon blocksy 36 are sills 37 upon which are supported transverse 'beams' 7 38, upon which rest shoes 39 formed by ex-' tensions of the sides of a metallic apron-,41 having an inclined upper surface 42. Sai

apron vcan be adjusted rotarily upon said f beams by means of a screw 43 havin a stem 44, whichpasses through a swivel s eeve 45 secured in a bearing 46 on one of said sills, which stem is provided with a collar 47 to prevent longitudinal movement in said A sleeve, thescrew 43 of said stem passin apron. By this means the rotary position o the upper portion of said apron can be adjusted. The lower provided with a vertica axle 50, shown in dotted lines in Fig. 4 by which said lower portion is revented y rom moving laterally while permitting the upper portion to turn about said axle. From a side of said apron extends an arm 51, the outer end of which is pivotally connected as shown'at 52 to the table 32 so that, upon the lateral adjustment of said a ron, sald table 32 is likewise rotatably a 'usted to set said rollers at a different angle in correspondence with the different position of the a ron.

Upon the rear end o the apron is mounted a roller 54 upon which is wound a band or sheet 55 of suitable material, metal or ortion thereof isy 'through a swivel nut 48 secured -1n sai v of the bottom ofsaid hopper, and moving i j distributed -evenly over-said. sheet material' j shaft of which are mounted infboxes 63 .ad`

. */justable vertically in standards 64 by mams otherwise, Whichrband passes over-"a roller 56 and then extends down over the upper surfaces of the a rontl between guide bars justment'f said, bars, and by meansof this hopper lastic` material isfed on to vthe up.- per surlace ofthe sheet material. The plastic material liowing through thejlowe'r side downward with the sheet nmteriahisfirst by means of af roller.62,vtheends of the of screws 65j. It then, stillmoving downward with the sheet material, passes. be-

' neath a tamping roller `66, of .like construc- -tion withthe first named/roller,- which eX- erts greater pressure upon the plastic material and` regulates the thickness ofthe layerl thereof. A wiper blade 67 is secured to the guide bar on the vside vof the apron from which the pile travels and-extends over said latter roller. Also secured to the same guid bar is one end of a stout spring arm 68 the other end of which carries bearings 69 for the shaft of a roller 70 having a rounded` edge adapted to engage the pile andprevent its moving toward the apron, since the pile has a tendency, owing to the 'pressure of, the sheet material thereon, to Amove to- Ward said apron. Secured to the ends of' the guide bars 57 adjacent tothe pile are the ends of a helical wall 71, which encirclesthe pileand isof substantially the same height as the layer of plastic material, which confines the edge of said plastic material between the pile and the sheet material being spirally wound therearound. This wall is j additionally supported by the end of a supporting arm72 secured to and extendlng upwardly from the lower portion of the guide bar from which the pole is traveling.

Any motive-power other than the electric motor herein shown may be employed to drive said mechanism.

From the above description of the apparatus its operation will be readily understood. By the power of the prime motor the truck is advanced longitudinally, thus advancing the pile lengthwise and. at the same time rotatlng said pile. A portion of the pile having been covered by hand with a layer of plastic material and by the end of the band, the apparatus is set in motion,

andthe plastichiaterial moves .down the tableinunison with the band, and, upon' ar`- iriving atthe pile, itis fed between said pile and sheathing ofl the band,"being confined to` its'- position between said pile and sheath-l ing by the flexible wally-71, as described.

Wl1en a' sullicient jlengthhas been socovered, the end ofl the sheathing yis vfinished by hand in any suitp able manner,"y`as bywiring the end of ltheband. By changing .the angle :of the apron, or by shaping the band,- the end of the sheathing may be formed in a conical shape.

The machine may bel used for other purposes,- as, for instance, for manufacturing cylinders or pipes of concrete orother plasj tic material by usinga collapsible core.
